not indicate a ram bottleneck. The virtual memory system often makes page exports to the memory segment, but the page import operation indicates that the server needs more memory, and the page import needs to copy the memory segment from swap disk back to RAM, causing the server to become slower.There are several ways to solve this problem:1. The simplest, increase the RAM;2. Reduce the need for RAM by changing the SGA;3. Reduce the need for RAM. (e.g., reduction of PGA)Reference Documentation:
